Health literacy is considered a determinant of self-management behaviors and health outcomes among people with diabetes. The assessment of health literacy is central to understanding the health needs of a population. This study aimed to adapt the Health Literacy Questionnaire (HLQ) to the Portuguese context and to examine the psychometric properties of a population of people with diabetes.
Data were collected using a self-administrated questionnaire from 453 people with diabetes in a specialized diabetes care unit. Analysis included item difficulty level, composite scale reliability, and confirmatory factor analysis (CFA).
The HLQ showed that the items were easily understood by participants. Composite reliability ranged from 0.74 to 0.83. A nine-factor CFA model was fitted to the 44 items. Given the very restricted model, the fit was quite satisfactory [χ = 2147.3 (df = 866), = 0.001; CFI = 0.931, TLI = 0.925, RMSEA = 0.057 (90% C.I. 0.054-0.060), and WRMR = 1.528].
The Portuguese version of the HLQ has shown satisfactory psychometric properties across its nine separate scales in people with diabetes. Given the strong observed properties of the HLQ across cultures, languages, and diseases, the HLQ is likely to be a useful tool in a range of Portuguese settings.
健康素养被认为是糖尿病患者自我管理行为和健康结果的决定因素。健康素养的评估对于了解人群的健康需求至关重要。本研究旨在将健康素养问卷（HLQ）适用于葡萄牙语环境，并检验其在糖尿病患者人群中的心理测量特性。
在一个专门的糖尿病护理单位，使用自填式问卷从 453 名糖尿病患者中收集数据。分析包括项目难度水平、综合量表信度和验证性因素分析（CFA）。
HLQ 显示，参与者很容易理解这些项目。综合信度范围在 0.74 到 0.83 之间。将 44 个项目拟合到一个九因素 CFA 模型中。考虑到非常有限的模型，拟合度相当令人满意[χ=2147.3（df=866），p=0.001；CFI=0.931，TLI=0.925，RMSEA=0.057（90%置信区间 0.054-0.060），WRMR=1.528]。
HLQ 的葡萄牙语版本在糖尿病患者的九个独立量表中表现出了令人满意的心理测量特性。鉴于 HLQ 在跨文化、语言和疾病方面的强大观察特性，HLQ 很可能成为葡萄牙语环境中一系列有用的工具。
